About this book

Gideon Ryker wakes from a coma at a French chateau where Foreign Legion veterans spend their final years. His body bears signs of torture, and his memory is gone—except for recurring dreams of a young girl's face. He doesn't remember his own name. He knows that joining the Legion offers a new identity and passport in exchange for a brutal life of service. It's a choice made only by those seeking to forget or escape their past. But Ryker's past has caught up with him. When a CIA hit squad arrives at the chateau, he realizes he remains a target. Ryker must uncover the answers: Where did he come from? Who is the girl in his dreams? And why do so many people want him dead?
